ADJUSTABLE-FLOW Application led January .4, 1921. Serial No. 435,012.

To all whom t ma/ z/ concern.'

Be it known that we, DAVID Gr.v LORRAINE and WILLARD L. BOROUGH,citizens of the United (States, residin respectively, at Los Angeles,county of s Angeles, and at Fullerton,l county of Orange, State ofCalifornia, have invented new and' useful Im- ,provements inAdjustable-Flow Nipples, of

which the following is a specification. Itis the object of the presentinvention to provide an adjustable ow-nipple parl j ticularly adaptedtobe employed in connection with oil wells. It has been found necessary toprovide in the pipe line from l an oil well, some regulating device forthe How of oil, and in `the present inventionl we provide a lregulatinnipple the passage through which may ie readily adjusted in size, soasto provide for any desired flow,

the' flownipple at thesame' time being so constructed as to preventcutting out of the same Vby the sand and the like passing throughthepipe line. l l

It is a. further "object of the invention to provide a constructionwhich will be inexpensive to manufacture and which will be durable andeiiicient in operation.

,A Further objects of the invention will be readily understood from the`following de- 'soription of the accompanying drawings,

in which,

Figure 1 is a plan view o'f a nipple constructed in accordance with theinvention.

' Figure 2 is a longitudinal section through the same.

vFigures 8 and 4 are transverse sections on the lines 3--3 and 4 4 ofFigure 2.

ln the drawings we have illustrated the iow nipple as employed in a-pipeline having the pipe sections 1 and 2, the nipple bemg positined betweensaid-sections-a-nd suitably attached thereto.

The nipple consists of a pipe 3 ha ving)v a bore 4 and threaded ends 5for detacha ly connecting the nipple to the pi e sections. The bore ofthe nipple is of uni orm width and is rectangular-in cross section.--The top of the bore shown'at 6, is parallel to the longitudinal axisofH the nipple, while the bottom of the same, shown at 7, is inclined soas to provide a bore of gradually taper'- ing Across sectional lareafrom one end of the nipple to the other.

rIhe means 4employed for controlling the vow through the nippleconsistsaofa wedge said opening. The opening 11 is continued shapedblock 8, litting snugly within the width of the bore, and also abuttingagainst the top of the bore. The lower side of the block is inclined Aasshown at 9, so as to extend parallel tothe base of the bore, and thisinclined surface is spaced from base 7 so as to provide for vthe passageof fiuid through the nipple. l v

It will be noted that the inclination Aof the underside of block 8 inconjunction with 65 the inclined base of the nipple bore, vpro-` videsla construction wherein longitiidinal adjustment of the block in 'thebore of the nipple, will cause variations in the size of the openingprovided through the nipple, and the device provides means foraccurately adjusting block 8 so that the flow may befreadily regulatedin this manner.

As an instance of this arrangement, the pipe 3 may be provided with atransverse opening llbcommunicating, with bore 4 at the block 8, saidopening being of sufficient length to permit of the desired longitudinaladjustment of the block which projects into C i through a casin l2projectin be ond' i -e. 3, and theendgof this casin isyprovihd with athreaded closure cap13.

The portion of block 8 which projects into opening 11 is shown asv adetachable vmember 14, having a `removable top 15, and cooperating halfbearings 16 formedv in the adjacent surfaces of said member and itstop.` Bolts 17 are received through top-"15 and member 14,'so as to'entend into kblock 8, and a longitudinally vextending actuating rod 19is received through bearings 16, and is held in position b passing thevbolts 17 through the same. y this arrangement it will be seen thatadjustment of rod 19 will move block 8 back and forth .for regulatingthe size of the flow opening through the nipple.

The rod 19 extends at each end transversely beyond casing 12 and at oneend is received-in a closed guide bearing 20 projecting beyond saidcasing, and at the other end extends through a bearing 21 formed in thecasing', and provided with packing 22 and a retaining nut 23.

The end of rod19 extending beyond the packing bearing is threaded asshown at 24, and isslidably mounted in a lug 25 projecting from pipe 3.Nuts 26 are threaded upon the rod/lso as to abut-against the re- .no

spective sides of lug 245,: so that ...by adjustmentof said nuts the rod19 may be accurately longitudinally" positioned andv locked vin anydesired position.

A gauge is provided lso that an opening lmay be formed in the nipple ofany predetermined size, through a ustment of lrod 19 and block 8 carriedthereby. For this purpose a scale 27, preferably graduated in sixteenthsof an inch up to one inch, is formed upon pipe 3, and an indicatorl pin28 carried by rod 19 cooperates with said graduations. 4

` It will thus'be seen that we haveprovided a readily adjustableflownipple, which is of 'simple but 'durable construction, and which is notsubject to cutting out by sand and the like.

It is to be noted that whilewehave ldescribed the invention as employein connection. with-'thepipe line from an oil well,

that the invention isv not limited to this use,

but is of general application, wherever -it is desired toaccuratelyregulate the iiow of -It will beapparent that various changes 'may bemade: in the construction as thus descrlbed without departing from thespirit ofv thef invention. A

What is -claimedis:

1. A flow nipple having a tapering bore,l

, fa longitudinallyadjustable tapering regulating memberreceived'therein and cooperating therewith,` said nipple having atransverse opening therein',`a block in said open- .ing and adjustablelengthwise of said nipple,

and means for connecting said block to said -regulating member.

2. A llowjnipp'le having a tapering bore, j da longitudinally adjustabletapering regulatving member received therein and cooperating therewith,said nipple having a transf versc opening therein, a block in said open-'in 4 and adjustable lengthwise of said nipple, a ongitudinallyextending operating rod,

nd means for connecting said rod ltosaid lock and said block to saidregulating member.

3. A low'nipple having a tapering bore, a longitudinally adjustabletapering regulating member received therein and cooperatingfftherewith,said nippleA having a trans- 'memben f nipple havin verse openingtherein, a block in said opening and adjustable lengthwise ofsaidnipple,-

a top for said block, said block and top having cooperating halfbearings formed therein, a longitudinall extending yoperating rodreceived in said arings, and connecting Ameans extending through saidtop, rod, and block and into said regulating member;

el. A flow jnipple having a tapering bore, a longitudinally adjustabletapering regulating member received therein and cooperating therewith, alongitudinally' extending operating `rod connected to said member andhaving a threaded end, a lug receiving said threadedend, and adjustingnuts threaded on said rod against the respective faces of said lug. t v

5.
